[gotcha] Failing to warn about grapefruit juice interactions when recommending or explaining statins

Always include a dietary warning against consuming grapefruit or grapefruit juice when discussing statins \(e.g., simvastatin, atorvastatin\), as it inhibits CYP3A4, causing toxic drug accumulation.

Journey Context:
Agents often list side effects like muscle aches for statins but miss the dietary interaction. Grapefruit contains furanocoumarins that irreversibly inhibit intestinal CYP3A4. This isn't a minor interaction; it can cause rhabdomyolysis \(muscle breakdown leading to kidney failure\) by spiking blood levels of the drug several-fold.
